Subject: drm/radeon/dpm: add late_enable for KB/KV
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d8852c3446ddeab300c4ae397d658b8715535102;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/radeon/dpm: add late_enable for KB/KV

Make sure interrupts are enabled
before we enable thermal interrupts.
Also, don't powergate uvd, etc. until after
the ring tests.
